I've encountered this issue during system-wide updates and found out that there are two branches of PHP available, thus I had to manually specify which package needs to be updated.

Also, when I encountered version conflicts, I found out that the best way to deal with them is by dropping out of X, into the good old terminal and run:

/usr/pkg/sbin/pkg_add -uu MyPackage

Last but not least, take a look at PKGDEPGRAPH(1).

Supposing you have PHP installed, here is a PHP script which creates a "raw" update script needed for a fail-safe system-wide update. It prepares an update which starts from the core dependencies (the most depended upon, like PERL) and works its way out to the leafs (those without dependencies, like TCSH).

After it generates the update sequence, YOU NEED TO REVIEW IT "LINE BY LINE" ... REMEMBER ... ALWAYS DOUBLE CHECK. Here is the script:

PHP Code:

#!/usr/bin/env php
<?php

/* *** PKGDEPGRAPH(1) *** */

ob_start();
$sysValue = system( 'pkgdepgraph -o' , $sysCode );
$strList = ob_get_contents();
ob_end_clean();

if ( $sysValue === FALSE || $sysCode ) { exit; }

/* *** TMP Directory *** */

$tmp = '/var/tmp/' . time();

$sysValue = system( "mkdirhier {$tmp}" , $sysCode );
if ( $sysValue === FALSE || $sysCode ) { exit; }

/* *** LIST Processing *** */

$arrList = explode( "\n" , $strList );

$dbList = array();

foreach ( $arrList as $key => $value ) {
    if ( !empty( $value ) && preg_match( '/label="\((\d+)\)\s(.+)"/' , $value , $matches ) ) {
        $order   = $matches[1];
        $package = $matches[2];
        if ( !array_key_exists( $order , $dbList ) ) { $dbList[$order] = array(); }
        $dbList[$order][] = $package;
    }
}

@file_put_contents( "{$tmp}/packages.lst" , $strList );
@file_put_contents( "{$tmp}/array.1.lst"  , print_r( $dbList , TRUE ) );

krsort( $dbList );

@file_put_contents( "{$tmp}/array.2.lst"  , print_r( $dbList , TRUE ) );

$sequence = "#!/bin/sh\n";

foreach ( $dbList as $arrLevel ) {
    foreach ( $arrLevel as $package ) {
        $sequence .= "/usr/pkg/sbin/pkg_add -uu {$package}\n";
    }
}

@file_put_contents( "{$tmp}/sequence.sh" , $sequence );
system( "chmod 0755 {$tmp}/sequence.sh" );
